Images and Depth
Images require more space when they use more color. The necessity of color is not always as necessary as it seems when considering making an impact on viewers. In many cases an image with less color is more effective in quicly appealing to a wider audiance. The need for color pixel pigment in the image also makes it harder for the image to load due to the spacial requirements. This need for space comes from the amount of different colored individual pixels which are required to make the image. Depth to an image is more than just in terms of light and shadow but also depth of relaitibility and usefulness.
